  • Non-Alcoholic Fatty Liver Disease
    Non-alcoholic fatty liver disease Description Non-alcoholic fatty liver disease (NAFLD) is a buildup of excessive fat in the liver that can lead to liver damage resembling the damage caused by alcohol abuse, but that occurs in people who do not drink heavily. The liver is a part of the digestive system that helps break down food, store energy, and remove waste products, including toxins. The liver normally contains some fat; an individual is considered to have a fatty liver (hepatic steatosis) if the liver contains more than 5 to 10 percent fat. The fat deposits in the liver associated with NAFLD usually cause no symptoms, although they may cause increased levels of liver enzymes that are detected in routine blood tests. Some affected individuals have abdominal pain or fatigue. During a physical examination, the liver may be found to be slightly enlarged. Between 7 and 30 percent of people with NAFLD develop inflammation of the liver (non- alcoholic steatohepatitis, also known as NASH), leading to liver damage. Minor damage to the liver can be repaired by the body. However, severe or long-term damage can lead to the replacement of normal liver tissue with scar tissue (fibrosis), resulting in irreversible liver disease (cirrhosis) that causes the liver to stop working properly. Signs and symptoms of cirrhosis, which get worse as fibrosis affects more of the liver, include fatigue, weakness, loss of appetite, weight loss, nausea, swelling (edema), and yellowing of the skin and whites of the eyes (jaundice). Scarring in the vein that carries blood into the liver from the other digestive organs (the portal vein) can lead to increased pressure in that blood vessel (portal hypertension), resulting in swollen blood vessels (varices) within the digestive system.

  • Analogy Between Non-Alcoholic Steatohepatitis (NASH) and Hypertension: a Stepwise Patient-Tailored Approach for NASH Treatment
    REVIEW ARTICLE Annals of Gastroenterology (2018) 31, 1-9 Analogy between non-alcoholic steatohepatitis (NASH) and hypertension: a stepwise patient-tailored approach for NASH treatment Yaron Ilan Hadassah Hebrew University Medical Center, Jerusalem, Israel Abstract Non-alcoholic steatohepatitis (NASH) is a common liver disorder worldwide. Although there has been improvement in our understanding of the natural history and pathogenesis of the disease, there is still no approved therapy for NASH. NASH shares many similarities with primary hypertension, in that both are extremely common disorders that can easily lead to serious complications if left untreated. Both conditions are viewed as “silent killers”, because the disease can progress over a period of time prior to the occurrence of potentially deadly outcomes. While attempts to find the “miracle pill” for NASH are unrealistic, we can make an analogy with the “stepwise combination” approach developed over the last few decades for the treatment of hypertension. In the present review, we summarize some of the similarities in the concepts that underlie NASH and hypertension. The development of a stepwise patient-tailored method for the treatment of NASH is presented. Keywords Non-alcoholic steatohepatitis, hypertension, treatment, non-alcoholic fatty liver disease Ann Gastroenterol 2018; 31 (3): 1-9 Introduction Hypertension (HTN) has been recognized for much longer than NASH and the two conditions share many similarities. Non-alcoholic fatty liver disease (NAFLD) is defined as the We describe some of the common features of both diseases in presence of a significant amount of lipid accumulation in the liver an effort to determine what hepatologists can learn from HTN without significant alcohol consumption [1].

  • Acute Severe Transaminitis As a Unique Presentation of Chronic Cholecystitis
    Open Access Case Report DOI: 10.7759/cureus.16102 Acute Severe Transaminitis as a Unique Presentation of Chronic Cholecystitis Huda Fatima 1 , Deepti Avasthi 1 1. Internal Medicine, St. Vincent Mercy Medical Center, Toledo, USA Corresponding author: Huda Fatima, [email protected] Abstract The hepatocellular function can be evaluated using aspartate aminotransferase (AST) and alanine aminotransferase (ALT) which are biochemical markers of the liver. Whenever there is an ischemic, toxic, or inflammatory injury to the liver, necrosis of the hepatocytes occurs and these biochemical markers are released into the circulation, showing an acute elevation in serum levels. In this case report, we discuss the unique clinical presentation of a female patient who came to the Emergency Room (ER) with acute onset chest pain with laboratory findings of elevated serum aminotransferases and cholestatic markers and was ultimately diagnosed with chronic cholecystitis. The usual clinical presentation associated with extremely elevated levels of liver enzymes can be one of three cases: acute viral hepatitis, toxin-induced liver injury, or acute ischemic insult to the liver. However, our patient was diagnosed with chronic cholecystitis despite her unique initial presentation of acute, severe transaminitis. While one may find elevated liver enzyme levels in acute cholecystitis, owing to the sudden nature of the inflammatory process, chronic cholecystitis is not known to cause high levels of serum amino transaminases or fulminant liver failure. Our case report indicates a diverse phenotype of chronic cholecystitis with an unusual presentation of acute, severe transaminitis. It helps expand the differential diagnoses of acute elevation of liver function tests (LFTs). Further studies are needed to explore the pathology behind chronic cholecystitis in order to understand its impact on liver damage.
